The problem was unknown to me and probably would be to any vehicle owner that is not a mechanic. I was driving a death trap and didn't know how easily it could have been a serious problem. The driver side leaf spring bracket had completely broke apart from the frame on the upper drive side corner in an area that without getting underneath the vehicle with a flashlight and specifically looking for would be impossible to see. The only reason I know about it now is because I took it for an inspection and it failed due to this structural defect which the technician informed me was a very common issue with the 2007 H3 vehicles. He said that if I had been on a highway at 65/70 mph and this thing broke completely free the axle would swing out behind the vehicle on the drive side and cause an uncontrollable crash that could lead to severe injury and possibly death

I have the well known issue with the passkey security system. Nothing is wrong mechanically with the car but the security system will not allow the truck to start, therefore leaving me randomly leaving me stranded. Much has been documented on this issue, yet gm has never done a recall.

So the part that is a malfunction is the rear doors weren’t made with any child lock and of course one of my kids opened the door while i was driving on the highway.I have a 3 and 5 year old and it scared me so bad I had to hurry and pull the hummer over and park and just held my son. I couldn’t even drive after that because of how bad it traumatized me. My mom had to come get and take me and my kids home and drive my hummer back home. Even though we didn’t crash or one of my kids didn’t fall out.it’s still a very serious safety hazard. I reached out to gm to see what my options were and there response was how gm made child locks in 2007 and up and that’s not the truth because mine is a 2007 and it clearly doesn’t have child locks. Then they later proceeded to tell me I should just sell my vehicle. I was so upset because if one of my kids would have fallen out and something happened I would do everything in my power to make sure they were held accountable and file a lawsuit against them. Yes The vehicle is available to inspect. My kids safety was at risk and then me braking and pulling off the highway in panic mode could have caused an accident.it’s been reported to gm and also local dealers. There was no warning just when it happened scared me so bad because my kids are in my back seat. The photos I uploaded are of the transcribed voicemails and I’m willing to also submit the voicemails from gm as well.

I bought my 2007 hummerh3 used w/124,000 miles. I've had it a month and already had it in mechanic shop due to not starting. The mechanic thought it was a fuel relay and charged me 258.00 parts/labor/tow. Today 11-16-21, only a day after I got it back, it stopped on me again!! Just had it towed again. Just learning that this is a common problem! Is anything being done to rectify this problem?

Went out to start H3, turned key, check engine light came on, the battery light came on and the anti-theft system light came on. Passlock/security system inside the steering column IS bad. Car won't start. IS unsafe and will strand owner without warning by not starting. goes into security mode. Was told to wait 10 min and try again. Can't turn it off at gas pump for fear of it locking me out and not starting. I had this happen to me 4 times in one day. so many complaints all over the internet and people trying to fix this issue. There IS even a company selling a part to bypass this and the security system which again IS another issue. gm IS clearly aware of this issue. This needs to be recalled. Stranding people can be very dangerous. If there IS an emergency and the car won't start. All around bad business by gm for not issuing this recall. this has nothing to do with mileage which gm manager said on the phone. These H3'S are know from this fresh off the dealership floor. People are being forced to take it to a dealership for repair and replacing the part when the labor costs more than the part. Seem like a monopoly for gm and its dealerships. I have seen anywhere from 1500-2000.00 to install and rectify this bad part at the gm dealerships.
